Mother of Pearl

Mother of Pearl, also known as nacre, is a beautiful organic gemstone material treasured for its luminous white coloration and delicate iridescent shimmer. Its soft, pearlescent appearance reflects subtle shades of cream, silver, pink, blue, and green as light moves across its surface.

Formed naturally inside the shells of certain mollusks, Mother of Pearl is composed of thin layers of calcium carbonate and organic material. These layers create its distinctive rainbow-like luster, making it a timeless favorite in fine jewelry and Southwestern designs.
